How to design and use 3d printable soldering stencils

In this post we present methods and software on how to design and use 3d printable solder stencils for your PCB and electronics projects.

Robert Kirberich developed a Python script to convert two Gerber files into a .STL that is 3d printable. It also works with Eagle files. It outputs the files into OpenSCAD .scad files and you can work on them form that environment.

Here is a video tutorial on how to use soldering stencils by SparkFun to stencil an Arduino Pro PCB:

Instructables user rmd6502 made a detailed tutorial how to design a 3d printed soldering mask for your electronics projects. he goes from Eagle EPS to PDF format, then PDF to DXF and then uses OpenSCAD to get the final STL.

He writes:

This is a neat way to save a bit of money when you order boards. Normally you pay an extra $25-50 for a solder stencil, either a silkscreen or a sheet of metal with holes where the solder paste needs to go
